Impact: Without the federal ITC, California homeowners face a 1.7-year longer payback period — paying $7,320 more out of pocket.

Net Metering Policy — California

How California compensates your excess solar production

NEM 3.0NEM 3.0 (Net Billing Tariff)

Significantly reduced export credits — substantially longer payback. Battery storage highly recommended.

NEM 3.0 (Net Billing Tariff) provides reduced export rates. Existing NEM 2.0 grandfathered systems retain full retail for 20 years.

What Solar Critics Say (And Why Context Matters)

Honest counterarguments to common anti-solar claims — with California-specific context. Tap each claim to expand.

1"The solar tax credit is dead, so the math doesn't work anymore."

There's truth here — the 30% residential ITC (25D) stepped down and expired for new installations. But the headline misses two things:

  • §48E manufacturing credit (qualified pipeline only). The §48E advanced energy manufacturing credit had a construction-start deadline of July 4, 2026 that has now passed. It is a manufacturer-facing credit, not a consumer credit — homeowners cannot claim it directly. Installers with safe-harbored pipeline projects may pass through lower panel/inverter pricing, but any specific dollar passthrough depends on the installer and is not guaranteed.
  • Lease/PPA passthrough can still deliver credit value to homeowners as reduced monthly payments or upfront savings on qualified pipeline projects — you don't need to wait for tax season.

Cash buyers in California still benefit from state and local incentives where available. The math changes — it doesn't break.

2"Solar takes 14+ years to pay back — that's not worth it."

14 years is a national average that hides enormous regional variation and ignores the time value of money. Payback depends far more on your local electricity rate and incentives than on any national number.

In California: the current payback is 5.8 years without the federal credit (and would have been 4.1 years with the former 30% ITC). For context, fast-payback states like Texas run ~8 years and slower states like New York ~12 years.

The real question is whether your payback — at 0.333/kWh and 5 peak sun hours — beats leaving that money in another investment.

3"Solar doesn't add home value — buyers see it as a liability."

Berkeley Lab (LBNL) research consistently shows a solar premium of about 4.1% home value increase — but with an important ownership caveat:

  • Owned systems add value (the ~4.1% premium).
  • Leased/PPA systems may be neutral or slightly negative — the buyer must assume the contract.
  • Newer systems (under 10 years old) appraise higher than systems near end of warranty.

The fix is simple: disclose ownership type and transfer any lease/PPA cleanly at sale. An owned, well-documented system is an asset, not a liability.

4"What about roof replacement? Solar makes it a nightmare."

This is a legitimate concern — and the right move is to plan for it rather than ignore it. Most composition shingle roofs last 15–18 years after panels go on.

  • Before installing: if your roof is over ~10 years old, replace it first. Roof work bundled with the install used to qualify for the 30% federal ITC under Section 25D, but that residential credit expired December 31, 2025 — a 2026 owned-residential system receives $0 federal credit. See current ITC status.
  • Removing & reinstalling panels for a reroof typically runs $1,500–$3,000.
  • Budget for it: set aside ~$2,000 at year 15 so you're not surprised.

A reputable installer will assess roof condition in their quote — ask explicitly, and fold a reroof into the project if the roof is aging.
